RIVE'IING MACHINE.

Application `ilel June 20, 1921. Serial No. 478,868.

To all whom "15 may concern.'

Be `it 'known that I, JOSEPH E. BATIE, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of `Michigan, have invented certain new and useful Improvements in Rivet-` ing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to riveting machines and is designed for use particularly in riveting cleats `upon tractor wheel rims.

In the usual construction of tractor wheel, the cleats extend diagonally of the rim or at anangle relative to the plane of rotation thereof, and these cleats are secured to the rim by several rivets. Heretofore, the cleats have been secured to the rims either by manually riveting the same or by riveting'in a machine in which each of the rivets for each cleat is individually operated `upon to form its head. These methods are obliectionable, first, because of `the length of time required to rivet the cleats upon the rim, and second, vbecause the `base flanges of the cleats may not be in Contact with the face of the rim throughout their length. This latter objectionl is due to the fact that the base iianges of the cleat may not contact with the face of the rim throughout their `length when placed thereon, and consequently when the hot rivets are individually operated upon to formtheir heads, they are very liable to bulge out inthe space between the base flange of the cleat and the face of the rim, and as a consequence, therivet head is weakened and the base flange of the cleat `is held out of contact with the rim face.

Vith my construction, these objections are avoided by first clamping the base iiange of the cleat against the `rim face and then simultaneously operating upon all of the rivets securing the cleat to the rim to form their heads.

Other objects of the invention are to provide a riveting` machine in which the horn carrying the rim is pivotally mounted at one end upon the frame, whereby the horn is permitted to swing `so that a rim may be readily `positioned thereon or removed therefrom, and also may be readily revolved thereon to a desired position for riveting the succeeding cleat; and to provide a riveting machine in which the rivet snaps for forming the heads upon the rivets will engage embodying my Vinvention anddiagrainmatically showing the pipe lines and valves controlling the operation of the machine;

Figure 2 is a side elevation thereof in which the`pipe lines and valves controlling the operation `of the machine are also diavgrammatically shown;

Figure 3 is a perspective view Aof the `machine cmittingthe "pipe lines and valves;

Figure `is a vertical cross section through the lower end of the machine; 4

Figures 5 and `6 are respectively, a top plan View and an end view of the horn;

Figure 7 is a toppplan view of the pad upon the horn; i i

Fig'uresSand 9 are respectively cross sections on the lines 8-8 and 9`9 of Figure 7.

The frame of the riveting machine comprises the parallel sides 1 and 2, the upper cross bars Band the lower `cross bar 4C.- The frame is suitably suspended byme'ans (not shown) connected to the uppercross bars 3. 5 is a horn which is connected at one end 'to the frame side 2 by the horizontal pivot adapted to be engaged by the bearing 8 at the lower end'of the support 9, the upper end of this support being rotatably and longitudinally slidably mounted'` upon the gudgeon 10 which forms part ofthe lower cross bar Il and extends through the frame side 1. 11 is a pad which is carried. upon the horn 5 and has extending longitudinally thereof, the convex face 12 of substantially the same radius as that of the wheel rim 13. Since the cleats 14 are arranged diagonally upon the face of the rim and since it` is desirable to have the row of rivets 15 extending parallel to the axis of and above the horn 5, the longitudinal axis of the pad 11 is arranged at such an angle to the longitudinalaxis of the horn vthat the row of rivets 15 fo-r securing the cleat to the rim will extend parallel to the axis of and above the yhorn 5 when the rim `is mounted upon the pad. p

Inthe method of riveting a cleat 14 to the rim 13 the cleat with the hot rivets 15 extending through apertures in the base lange 16 of thercleat is placed upon the rim 13 [Himse- To .clampthe base-flange 16 of the `cleat 14 firmly against the'rim 13 and to simultaneously form. headsupon the inner-ends of the row of rivets 15 to `secure the cleat to the rim, I have provided the following construction:

`17' "is ,a cylinder suspended from the horn 5. 18` is a piston rod` extending from the lower end of the cylinder 17 and having at its lower end the enlargement 19. V2O are rods extending through lugs 21 and 22 upon opposite sides of the horn, 5, these. rods being connected to the` enlargement. 19 and to the padr 11. rlhe Ipistion in the cylinder 17 -is adapted to be raised by means of compressed air entering .through thepipe 23 and controlled by the valve 24,`which latter hasthe operating handle 25 adapted to cylinders arranged in staggered relation and pivotally suspended from the upper cross bars 3 of the frame there beino' the saine number of cylinders as rivets15(in the present instance 4). Extending through. the

\ lower endof each cylinder 27 is the piston Vrod 28 which is pivotally connected to the outer end `of a bell crank 29. This bell l crank has the hub portion 30 which is jour- `nalled upon the shaft 31 extending between the frame sides 1'and 2-and the bell crank has. the depending arm 32 which `is pivotally secured yto thebifurcations 33 at the upper end-of a link 34. The lower end o't .this link has the bifurcations 35which are `pivotally connected to a plunger which longitudinally slidably engages 'in a suit able bearing 1n the lower cross arni 4ot the `frame.

37 is a corresponding rivet snap 36 having av recess vin its upper face for forming the head upon thelower end of a rivet 15. VThe rivet snap 38 slidably engages infthe pad 11 and is mounted upon the horn To ladjust the height of this rivet snap so that its upper face-'will extend the proper distance above theA convex face 12 of the pad when the latter is in its lowermost position,

there is the set screw 39 threadedly engag- 27V are ing in the horn 5 and adapted to engage the lower end of the rivet snap. 4

lThe pistons in the cylinders 27 are. also adapted 'to be actuated by compressed air which enters the cylinders through the pipes 40 and is controlled by the four-way valve 41 having the operating handle 42.

In operation when the rim 13 has been correctly positioned uponthepad 11 and the cleat l14 with the hot rivets, 15 extendingthrough its base flange v16 has been positioned upon therim withthe lower ends of the hot rivets extending through the previously formed apertures in the rim, the foot` pedal 26 is depressed to open the valve 24 to allow compressed air to enter the cylinder 17 and raise the piston therein, thereby, raising the pad 11 through the rods 2O and piston rod 18.' rIhe raising of the pad 11clamps the base flange 160il the cleat `14?against the :tace of the rim 13. The neXt operationv is `the opening of the four-wayg l.valve 41 to allow lcompressed air to enter rivet snaps 37, as well vasthe pad 11, do-wn-v wardly by means of the piston rods 28, bell cranks 29, and links 34. One of the piston rods 28 upon its downward movementv engages the extension 43 of the operating rod 25 of the valve 24 to shut'ofr1 the supply of compressed air to the cylinder 17 and to permit lof its escape from the cylinder, the

air inthe cylinder 17 having been further compressed by reason of the downward `movement of the pad 11 actuated by the plunger-s 36. 'lChus upon continued down;

wardr movement of the plungers 36 with their rivet snaps 37, the pad'll moves down- `wardly therewith and permits of the lower ends of the rivets 15 finally coming in contact with the rivet snaps 38` carried upon the horn to. form heads upon` the lower ends. To clamp the base liange 16 ofthe cleat against thel face of the rim uponreleasing of the air pressure in the cylinder 17,\there are coil Vsprings 4.4 for yieldably holding the pad 1l inits upper position. These coil springs surround the rods 2O and abut against the lower lugs 21Iupon the horn 5 rand against collars 45 upon'the rods. f

For the purpose of correctly forming the headsl upon `the lower ends of the rivets 15,

the axes of the outer apertures in the padl.1 and in which the rivet snaps 33 slidably en- Figures 6 and 9, the angle ot'inclination being substantially four degrees from vertical, Also thedireetion of movement of the outer rivet snaps 37 mounted in their respective plungers 36 are correspondingly inclined. `With this arrangement, the different degrees of ,inclination-oi' the rivets 15 gage, are inclined as shown particularly in relative to each lother are taken care of.

vThe reason for the different degrees of ini but is oifset from the others peripherally of the rim.

Since the weight of the horn 5 with the pad 11 and its actuating mechanism is considerable, I have provided power means for swingingthe horn. Indetail, 46 is a cylinder pivotally mounted upon the frame side 2 at 47. 48 isa piston rod extending through the outer end of the cylinder 46 and Apivotally connected to itl/ie bracket -49 rigidly secured atl its lower end to the plvoted end of the horn. The piston in the cyl- -inder 46 is adapted to be actuated by compressed airwhiclrenters through the pipe 50 and is controlled by the valve 5l having the actuating handle 52. Thus, with this construction when it is desired to lower the horn romftheposition shown in full lines in Figure l', the support 9 is moved longitudinally upon the gudgeon l to the position indicated by dotted lines when the horn isfree to swing downwardly-` To raise Ithe horn, the valve l is opened which permits `air tol enter through the pipe into the cylinder 46 and force the piston rod 48 `outwardly, which through the bracket 49 swings the `horn 5 upwardly so that its gu-dgeon 7 :is in `position to be engaged by the; bearing 8l of the support 9. h To .position the horn in its raised posivti-on, the same is preferably provided with `the progection or pin 53 near its free end which 1s adapted to engage m a correspondinglyfshaped recess in the lower end of the .trame side l.

. It will also be noted that the lower cross bar 4 of the frame has the gudgeon 54 eX- tei-rding through the frame side 2 and engaging in the bracket 55 which latter has the pivot portions 56 and 57 respectively for the pivots 6 and 48. This bracket is secured against the frame side 2 by suitable means such as the stud bolts 58.
